Application filed November 7, 1917. Serial Ito. 200,660.

' be a full, clear, and exact description of the invention, such as willenable othersskilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to thefigures of reference marked thereon, which form ,a part of thisspecification.

My invention relates to a method for providing refrigeration and forcooling and ventilating the interior of dwellings or other structures orplaces, and more particularly, to that manner of cooling in which,heretofore, a current of air hasbeen caused to flow through pipessubmerged in or covered by a stream or well or cool earth or anartificial body of ice, the air being discharged into the places to becooled. In the efforts heretofore made to cool the inflowing air byemploying the earth or bodies of water as the cooling medium, thetemperature of the cooling medium has not been found sufiiciently low,to materially affect the temperature of the air passing through thepipes.

Where the air has been passed through pipes artificially covered by ice,the efi'ect has, of course, been more pronounced, but the enpense andcare incident to this method have prevented its general adoption.

My invention is designed to overcome the difficulties here indicated,and, to this end, to provide as a cooling medium for the currents of airemployed, a body of ice which in severe winter weather is by the actionof the elements allowed to form in a suitable receptacle adequatelyprotected against heat absorption, and to then utilize the ice thusformed,and while in place,as a cooling medium, thus dispensing with thehandling, storing andtransportation of ice. In the severest part of thewinter the apparatus may be used to introduce fresh air into houses,tempered by passing the air through 'the water of higher temperature inthe trench or tank. Should winter ventilation be an important endsought, two or more trenches of water may be provided through which theair pipes may be utilized one by one, for the purpose of passing freshair into the'building, While they water in. the

trenches is being frozen. In this way comparatively warmer air may beprovided for ventilating purposes instead of air of outside temperature,thus conserving the heat of the building.

The single figure of the accompanying drawing represents in centralvertical sec tion an illustrative example of a dwelling and an ordinaryice-box operatively connected with a cooling device,- constructed inaccordance with the principle hereindicated.

In the drawings, 1 is an elongated tank which, for illustration, may be,say, six feet deep, five feet wide and twenty feet long.

This tank should be buried several feet below'the surface of the groundand should be located in some exposed place where the winter wind andair can have access to its chamber. lVhile I have indicated a tank,which may be of wood or concrete or such other material as may bedesired, a simple trench of proper dimensions covered with. boards andprotected by 'a sufficient depth of earth, as has been described, will,in proper soils, be found sufiicient and more economical.

The chamber 2 of the tank is provided with a manhole 3 having a tightcover 4. 5 is a pipe, of which there may be as many as may be desired,leading through the length of the chamber 2 and into one or more airducts 6, provided with suitable registers 7, by means of which airpassing through the pipe 5 is distributed in the house as indi cated bythe arrows. A branch pipe 8, leading from the pipe 5 into a refrigerator9, conducts air to the refrigerawr from which it flows through pipe 10to the top of the building. At the top of the building is a ventilatorthrough which air may escape. If, in addition to the upward currentcaused by the rarefaction of the air as it becomes warmed or heated,additional current is required, fan 11 driven by an electric motor 12,located as may be desired in the path of the air current, may beemployed to cause the air to traverse the building and to flow upwardlyand outwardly. It will be under stood that while the cooling apparatusis in operation the doors and windows of, 1 the house should remainclosed in order that the draft through the cooling pipes be not broken,I

The pipe 5 is pro-videdwith an inlet-pipe 13 having a rotatablemouthpiecal which is automaticallyheld presented to the Wind by means ofan. attached vane 15. 16 is an outlet-pipe connected with pipe .5 at ornear the end opposite the inlet-pipe-13 and is provided with a suitablevalve 17 by Which-the opening through the pipe is controlled.

The operation of my device is as follows: The chamber 2 being partlyfilled with Water, the manhole 8 is left uncovered, and

winter air is allowed to flow through the pipesl3 and 16. Ice is nowrapidly formed in the chamber of. the tank or trench. As the freezingproceeds water is added until the chamber is filled with a solid blockof ice. Now the manhole is covered and protected; the valve in theoutlet pipe is,closed, access of Warm air is prevented and the ice isconserved until its use is required iii the hot Weather of thesucceeding summer.

' It will be seen that so large a block' of solid ice Willlast muchlonger than would smaller pieces; that thefilling ofthe'chamber Withiceby the method proposed evercomes the trouble, Waste and expensenecessarilyattendant upon the introduction of ice brought from adistance, and that the chamber with a suitable body of Water, then bypassing through such body ct water natural currents of air of freezingtemperature, and then,while the ice thus formed in said chamber remainsin place,passing a current of air through suitable comluitsinvested insuch ice into the place to be cooled.

In testi nony whereof I ailix my signature in presence of two Witnesses.
